Buying streak — 9 quarters in a row
For 9 consecutive quarters, more hedge funds added NBBK than sold it. That's a consistent pattern of professional buying — not a one-time trade. When institutions keep buying quarter after quarter, it usually means they see a multi-year opportunity, not just a short-term momentum flip.

At the ownership peak (100% of max)
100% of all-time peak
157 hedge funds hold NBBK right now — the highest count in 3.0 years. When ownership is this concentrated, any bad news can trigger a chain reaction: one big fund sells, others follow. This is a classic 'crowded trade' — high popularity doesn't equal safety.
🚀
Fast accumulation — +40% more funds vs a year ago
fund count last 6Q
+45 new funds entered over the past year (+40% YoY). That's a rapid rush of institutional money. Fast accumulation often signals a major thesis — but it also means the stock could fall quickly if that thesis breaks.
🟢
More buyers than sellers — 68% buying
109 buying51 selling
Last quarter: 109 funds were net buyers (34 opened a brand new position + 75 added to an existing one). Only 51 were sellers (36 trimmed + 15 sold completely). A clear majority buying is a strong confirmation signal.
